[Waiting Room]

The waiting room (courtyard) is the place where you will spend most of the time until the coliseum opens up. The waiting room serves as a hang out for all participants. After each match, the participants will always be teleported back to the waiting room until the next match begins.

While the coliseum is open, any new players that join the waiting room will be entered into the queue and will be matched up once the next round starts.

There are a total of 5 NPCs in the Courtyard, however the most important 2 are Arena Guard - Raul and Merchant - Renost
